CNMG120412-NMS WSM10S — Turning indexable insert, Tiger·tec Silver, 1.2 mm nose radius | Walter Tools

The CNMG120412-NMS WSM10S is a Tiger·tec Silver-coated turning indexable insert engineered for demanding machining of rostfreier Stahl and heat-resistant superalloys, offering durable edge stability in heavy-duty turning applications

• Tiger·tec Silver coated grade WSM10S
• Optimised NMS chipbreaker
• Rhombic 80° shape, 1.2 mm nose radius

Reliable machining of rostfreier Stahl and heat-resistant alloys

The WSM10S grade, part of the Tiger·tec Silver series, is formulated for exceptional thermal stability and reliable chip formation when turning rostfreier Stahl and Superalloys (ISO groups M and S). The coating technology reduces friction at the cutting interface and helps avoid built-up edge under elevated temperatures. As a result, the insert maintains a stable cutting edge over multiple components, which supports process security and reduces unscheduled tool changes in production environments. For shops moving between conservative and more aggressive feeds, this grade delivers predictable behaviour without sacrificing component finish.

Consistent surface quality and strong edge geometry

The Rhombic 80° form combined with a 1.2 mm corner radius provides a balanced compromise between profile strength and achievable surface finish. The 0° (negative) relief angle increases the insert’s robustness under interrupted or heavy cuts, while the NMS chipbreaker assists secure chip control and uniform chip segmentation. Together these characteristics enable a smooth part finish and reduced rework rates. For operators less familiar with geometry trade-offs, this combination simplifies the selection process by favouring edge security and repeatable results over marginal gains in cutting speed.

Predictable productivity and reduced process risk

By favouring thermal resistance and edge stability, this insert supports longer tool life and more consistent cycle times, contributing to measurable productivity gains on batch and serial production. The WSM10S grade is intended to deliver consistent tool life across similar component families, which helps planning of tool changes and inventory. Where process reliability is a priority, the insert’s behaviour reduces variability and contributes to leaner production sequences, allowing machine time to be deployed more efficiently and costs per part to fall over time.

Easy integration and application guidance

The insert’s designation and geometry follow established ISO indexing standards, making it straightforward to fit into common CNMG-compatible toolholders. Its NMS chip control geometry and Tiger·tec Silver technology make it suitable for both roughing and semi-finishing strategies on rostfreier Stahl and similar alloys. For customers seeking specific cutting data or validation within a machining cell, Metav Werkzeuge provides application advice and can support selection of holder and cutting parameters to match feed rates and depth of cut demands while avoiding on-site demonstrations.

FAQ

Which materials is this insert best suited for? The insert is specified for rostfreier Stahl and heat‑resistant superalloys (ISO groups M and S); the WSM10S grade and Tiger·tec Silver coating ensure thermal resilience during turning of these materials.

What chip control does the insert provide? The NMS chipbreaker on the CNMG120412-NMS insert promotes secure chip segmentation and manageable chips across a range of feeds, improving surface quality and operator safety.

How does the geometry affect cutting performance? The Rhombic 80° form with a 1.2 mm nose radius and 0° negative relief increases edge strength and resists fracture under interrupted cuts, supporting longer service life and stable finishing.

Is the insert compatible with standard CNMG toolholders? Yes, the designation follows standard CNMG indexing and fits holders designed for that insert size; toolholder selection should consider clamping style and recommended cutting parameters.
